Tyre tread for icy roads - has no spikes but contains suction cup recesses to improve adhesion to road surface

摘要

A tyre tread to provide a good grip on ice or compacted snow comprises a coarse tread pattern on one side (half-tread) and a fine pattern on the other. In one or both of these regions, blind holes acting as suction cups are incorporated. These improve the grip and eliminate the need for spikes.
